Particles don't follow curve
There is couple of thing you should do.
1. Switch direction of your path
Enter Edit mode and in N-panel find Curve Display -&gt; Normals, make it bigger to see actual direction of the curve. You need to keep direction &quot;from the particle system&quot;. So select every vertex and hit W -&gt; Switch Direction
2. Participant elements of Particle Physics have to be on the same layer
Right now your Particle System and Curve guide force are placed on different layers. Move the Curve on the same layer where Particle System is.
3. Check &quot;Path Animation&quot; option in curve's settings
Curve guide force will not be working without enabling this thing
